This is the first of three essential reference volumes for those concerned with the installation and servicing of domestic and industrial gas equipment. This volume explains the basic principles underlying the practical and theoretical aspects of installing and servicing gas appliances and associated equipment, from the basics of combustion, to burners, pressure and flow, transfer of heat, controls, as well as materials and processes, electrical aspects, and metering and measuring devices. The revised fifth edition is brought fully up to date with current Standards and legislation to reflect recent developments in industry, in line with requirements of the ACS Certificates of Competence and NVQs. Covering both natural gas and liquefied petroleum gas, the many illustrations and worked examples included throughout the text will help the reader to understand the principles under discussion. Volume 1 of the Gas Service Technology Series will enable the reader to put into practice the safe installation and servicing procedures described in the companion volumes: Domestic Gas Installation Practice (Volume 2), and Industrial and Commercial Gas Installation Practice (Volume 3). Combining a comprehensive reference with practical application in real-world engineering contexts, Volume 1 provides an essential handbook for all aspects of fundamental gas servicing technology, ideal for both students new to the field as well as professionals and noneoperational professionals (e.g. specifiers, managers, supervisors) as an ongoing source of reference.

The introduction of public key cryptography (PKC) was a critical advance in IT security. In contrast to symmetric key cryptography, it enables confidential communication between entities in open networks, in particular the Internet, without prior contact. Beyond this PKC also enables protection techniques that have no analogue in traditional cryptography, most importantly digital signatures which for example support Internet security by authenticating software downloads and updates. Although PKC does not require the confidential exchange of secret keys, proper management of the private and public keys used in PKC is still of vital importance: the private keys must remain private, and the public keys must be verifiably authentic. So understanding so-called public key infrastructures (PKIs) that manage key pairs is at least as important as studying the ingenious mathematical ideas underlying PKC.

In this book the authors explain the most important concepts underlying PKIs and discuss relevant standards, implementations, and applications. The book is structured into chapters on the motivation for PKI, certificates, trust models, private keys, revocation, validity models, certification service providers, certificate policies, certification paths, and practical aspects of PKI.

This is a suitable textbook for advanced undergraduate and graduate courses in computer science, mathematics, engineering, and related disciplines, complementing introductory courses on cryptography. The authors assume only basic computer science prerequisites, and they include exercises in all chapters and solutions in an appendix. They also include detailed pointers to relevant standards and implementation guidelines, so the book is also appropriate for self-study and reference by industrial and academic researchers and practitioners.

The concept of preventive conservation has successfully introduced the knowledge that "prevention is better than cure" into the built heritage sector. The benefits of this approach are the cost-effectiveness, the improved protection of heritage values, the reduced risk for accumulating deterioration and additional damage, the prolongation of the physical service life of buildings and building parts and the empowerment of local communities in dealing with heritage. Increasingly, arguments rise against reactive treatment patterns, which result too often in postponed interventions and increasing costs for restoration. WTA-Nederland-Vlaanderen, the Raymond Lemaire International Centre for Conservation and the Civil Engineering Department of KU Leuven jointly organised an international conference on preventive conservation approaches - including climate and damage monitoring - and how to implement these monitoring tools within a systemic approach. The conference took place in context of the international WTA days, 3-5 April 2019, and the 10th anniversary of the UNESCO Chair on Preventive Conservation, Monitoring and Maintenance of Monuments and Sites (PRECOM(3)OS). The contributions meet the increasing demand for information, case studies and practical examples to support the transition towards more preventive rather than reactive conservation actions. The volume aims at academics and professionals involved or interested in the conservation of buildings, building parts and heritage.

The Construction Contracts Act 2013 introduces adjudication for the construction industry in Ireland for the first time. The essence of adjudication is in providing a means whereby disputes as to payment under a construction contract are resolved quickly and cheaply. The key feature distinguishing adjudication from other processes is that the money found due by the adjudicator must be paid pending the outcome of arbitration or litigation. Its primary function, therefore, is to ensure cash flow for contractors and sub-contractors. Leading construction lawyer Anthony Hussey's new book is the first to provide a section by section analysis of the Act itself, an analysis of the Code of Practice, and a discussion of the likely constitutional issues to which the legislation will give rise. This practical legal reference is aimed at all those involved in construction contract disputes, be they lawyers, architects, engineers, quantity surveyors, contractors and sub-contractors.

This book comprises the proceedings of the conference "Future Production of Hybrid Structures 2020", which took place in Wolfsburg. The conference focused on hybrid lightweight design, which is characterized by the combination of different materials with the aim of improving properties and reducing weight. In particular, production technologies for hybrid lightweight design were discussed, new evaluation methods for the ecological assessment of hybrid components were presented and future-oriented approaches motivated by nature for the development of components, assemblies and systems were introduced. Lightweight design is a key technology for the development of sustainable and resource-efficient mobility concepts. Vehicle manufacturers operate in an area of conflict between customer requirements, competition and legislation. Material hybrid structures, which combine the advantages of different materials, have a high potential for reducing weight, while simultaneously expanding component functionality. The future, efficient use of function-integrated hybrid structures in vehicle design requires innovations and constant developments in vehicle and production technology. There is a great demand, especially with regard to new methods and technologies, for "affordable" lightweight construction in large-scale production, taking into account the increasing requirements with regard to variant diversity, safety and quality.

Practical production of ordinary and special, high performance concretes and their behaviour and properties when fresh are the main themes of this book. It derives from the International RILEM Conference held in Paisley, Scotland in June 1996, and represents the culmination of the work of two RILEM Technical Committees (145 WSM Workability of Special Mixes, and 150 ECM Efficiency of Concrete Mixers). Very significant advances have been made recently in the development of concrete with outstanding properties. Such advances in research must be matched by progress in the technology of concrete production. This book focuses on production methods and on workability and handling, two fundamental and closely linked stages of the concrete construction process. It has a strongly practical emphasis, with many contributions showing how to build effectively using the many high performance concretes which have progressed from research into construction in recent years. The main themes covered are: production mixers and mixing processes; production methods; sprayed and very dry precasting mixes; fibre reinforced concrete; flowing and superfluid mixes; rheology; test methods; mix design and models; special cements and concretes.

This book focuses on solar energy conversion systems that can be implemented in the built environment, at building or at community level. The quest for developing a sustainable built environment asks for specific solutions to provide clean energy based on renewable sources, and solar energy is considered one of the cleanest available energy on Earth. The specific issues raised by the implementation location are discussed, including the climatic profile distorted by the buildings, the available surface on the buildings for implementation, etc. This book also discusses the seasonal and diurnal variability of the solar energy resource in parallel with the variability of the electrical and thermal energy demand in the built environment (particularly focusing on the residential buildings). Solutions are proposed to match these variabilities, including the development of energy mixes with other renewables (e.g. geothermal or biomass, for thermal energy production). Specific solutions, including case studies of systems implemented on buildings all over the world, are presented and analyzed for electrical and for thermal energy production and the main differences in the systems design are outlined. The conversion efficiency (thus the output) and the main causes of energy losses are considered in both cases. The architectural constraints are additionally considered and novel solar energy convertors with different shapes and colors are presented and discussed. The durability of the solar energy conversion systems is analyzed considering the specific issues that occur when these systems are implemented in the built environment; based on practical examples, general conclusions are formulated and specific aspects are discussed in relation to experimental results and literature data. With renewables implemented in the built environment likely to expand in the near future, this book represents welcome and timely material for all professionals and researchers that are aiming to provide efficient and feasible solutions for the sustainable built environment.

Both the number and percentage of people living in urban areas is growing rapidly. Up to half of the world's population is expected to be living in a city by the end of the century and there are over 170 cities in the world with populations over a million. Cities have a huge impact on the local climate and require vast quantities of energy to keep them functioning. The urban environment in turn has a big impact on the performance and needs of buildings. The size, scale and mechanism of these interactions is poorly understood and strategies to mitigate them are rarely implemented. This is the first comprehensive book to address these questions. It arises out of a programme of work (POLISTUDIES) carried out for the Save programme of the European Commission. Chapters describe not only the main problems encountered such as the heat island and canyon effects, but also a range of design solutions that can be adopted both to improve the energy performance and indoor air quality of individual buildings and to look at aspects of urban design that can reduce these climatic effects. The book concludes with some examples of innovative urban bioclimatic buildings. The project was co-ordinated by Professor Mat Santamouris from the University of Athens who is also the editor of the book. Other contributions are from the University of Thessaloniki, Greece, ENTPE, Lyons, France and the University of Stuttgart, Germany.

This book introduces the concept of Intelligent Buildings to the wider construction community. Edited by the Father of Intelligent Buildings, Derek Clements-Croome, the book explains that intelligent buildings should be sustainable, healthy, technologically aware, meet the needs of occupants and business, and should be flexible and adaptable to deal with change. This means the processes of planning, design, construction, commissioning and facilities management including post-occupancy evaluation are all important. Buildings comprise many systems devised by many people and yet the relationship between buildings and people can only work satisfactorily if there is an integrated team with a holistic vision.

This volume emphazises the most recent advances in fracture mechanics as specifically applied to steel bar reinforced concrete. Fracture mechanics has been applied to plain and fibre reinforced concrete with increasing success over recent years. This workshop extended these concepts to steel bar reinforced and pre-stressed concrete design. Particularly for high strength concrete, which is a very brittle material, and in the case of large structural members, the application of fracture mechanics appears to be very useful for improving the present design rules. The pre-eminent participants at the Turin workshop contributed extensive expert opinions in four selected areas for which a rational approach, using fracture mechanics, could introduce variations into the concrete design codes: size effects; anchorage and bond; minimum reinforcement for elements in flexure; and shear resistance. The 23 chapters logically address these themes and demonstrate the unique ability of fracture mechanics to capture all the experimentally observed characteristics. The book is primarily directed to the researchers in universities and institutions and will be of value to consultants and engineering companies.
